I have one in my gym from time to time (I think he still deploys). Has one of the fantastic artificial legs that is a marvel. The first day he came in I chatted him up about it and he was happy to talk. And yes, he is in amazing shape. (And no, I wasn't hitting on him though I didn't mind looking.)

These men are all impressive and inspiring. There is a man with a prosthetic leg who I see in the gym that I use on base. When he is there he is always one of those in the best shape, and this is in a gym that is full of Marines and SEALs. Worthy of admiration on many levels.
